Hi John!
I am having some issue for a question in the BPP kit.
Corrie produces three products, X, Y and Z. The capacity of Corrie’s plant is restricted by process alpha. Process alpha is expected to be operational for eight hours per day and can produce 1,200 units of X per hour, 1,500 units of Y per hour, and 600 units of Z per hour.
Throughput/unit for product:
x =80
y=80
z=200Determine the efficiency of the bottleneck process given the output achieved is 6,000 units of X, 4,500 units of Y and 1,200 units of Z.
-The answer is 125% and the workings done is a bit complicated to understand.
-Could you please help to obtain the answer?Thanks.
Than
Since the machine can produce 1,200 units of X in one hour, then for the actual production of 6,000 units you would expect it to take 6,000/1,200 = 5 hours.
Similarly you would expect it to take 3 hours to produce 4,500 units of Y, and 2 hours to produce 1,200 units of X.
So in total it should have taken 5 + 3 + 2 = 10 hours.In fact, it only worked 8 hours a day, and so it was producing more than expected and was more efficient. 10 hours worth of work in only 8 hours means the efficiency is 10/8 = 125%
